OK, I'll say it: Nathan Lane. All the hamming it up, the knowing wink and a nod to the audience, the staged out of character moments, etc, etc. There are some others that I like, but I don't get all the fuss over, and most of them have already been named (Cheno, Esparza, etc.).
And while I really like Sutton Foster, I don't think she should get a Tony nom just for showing up. She's been smart and lucky in finding roles to originate, but she's due to find something a little more challenging than Young Frankenstein and Shrek.
